A legitimate question arises whether the desired values of \(A_{\chi }\)  are attainable within the considered model. As one can readily see, the desired values of \(A_{\chi }(=2EV_{\chi })\) , can be achieved for UHE (\(\sim \)  1 PeV) neutrinos for the mass and coupling accommodating B-anomalies. For example, the best scenario to reconcile the B-anomalies is given by \(m_{\chi } \)  = 10 GeV and \(m_{\phi }\)  = 358 GeV for \(\lambda _{\mu } = \sqrt{4\pi }\)  [1]}. For these values, the \(A_{\chi }\)  corresponding to 1 PeV neutrinos is \( 0.9\, \rm eV^{2}\) .
